Hi guys

Quite often I will turn up a one-off on the lathe, then part off and turn it round for facing. I will want to turn to a particular length, but I want to use jog as it is quicker than writing a program.

Would it be possible to have a variable limit that you could drive the machine against and it will stop without tripping any limits or anything like that.

e.g. I want to remove 34 thou
set 'soft limit' to Z-0.034
Jog to first cut e.g. Z-0.06
Jog to second cut Z-0.016
Jog to Third cut Z-0.029
Jog to fourth Cut Z-0.034 - machine won't go past this point.

Cheers

You could try doing this by the MDI line,

Just type G01 z-.006, do your cut, then type G01 z-.016, do your second cut, and so on and so forth.

Or you can set a custom step increment in the jog window, the increment would be the total depth divided by the number of cuts, in your example it would be 0.0085", the put mach in jog step mode instead of continuous, and just click the -z jog button once before each cut, the z axis should move just that amount.

Hi Fernando

That can be done but it is much quicker to jog with the keys particularly when the depth of cut ain't critical.
